Dajinshan W-Sn deposit is located in the center of Daganshan arcuate fault zone with strong magmatic activity and complex structures. W-Sn ore-bodies are mainly occurred in main fault and flanking tectonic fissures with nearly parallel output, the main mineralization types are quartz-vein type, tectonic crushed zone-quartz vein complex type and alteration rock type. According to the latest mineral exploration results, it is expected that the entire mining area of WO₃+ Sn resources greater than 80 000 tons, and the mine located above the base level of erosion, easy to adopt and election, could become a new large-scale tungsten mineral resource base in Guangdong Province.oft-com:office:office" />
